Solving Coplanar Power-Limited Orbit Transfer Problem by Primer Vector Approximation Method

الملخص EN

The coplanar orbit transfer problem has been an important topic in astrodynamics since the beginning of the space era.

Though many approximate solutions for power-limited orbit transfer problem have been developed, most of them rely on simplifications of the dynamics of the problem.

This paper proposes a new approximation method called primer vector approximation method to solve the classic power-limited orbit transfer problem.

This method makes no simplification on the dynamics, but instead approximates the optimal primer-vector function.

With this method, this paper derives two approximate solutions for the power-limited orbit transfer problem.

Numerical tests show the robustness and accuracy of the approximations.
